PHONOGRAPHIC CLOCK.

SPECIFICATION forming part of Letters Patent No. 652,152, dated June 19,1900.

Application filed July 15, 1899. Serial No. 723,953. (No model.)

To all whom it may concern.-

Be it known that I, ERWIN TREITSCHKE, a citizen of the Kingdom ofSaxony, residing at Dresden-Blasewitz, in the Kingdom of Saxony, GermanEmpire, have invented certain new and useful Improvements in ClocksCombined with a Phonograph or the Like; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the-art to which it appertains tomake and use the same.

lVith the great demands to which at the present day people areindividually subject if they would compete with their fellows and byreason of the corporeal and mental strain thereby occasioned nervousnesshas greatly increased, so'much so that it may even be observed inchildren. To such as suffer from nervousness many kinds of noises arevery distressing, as the striking of a clock, which to many sufferersseems to sound against the head. Many cannot follow their employmentduring the time of striking, because of inability to concentrate theirthoughts, and often many cannot follow the number of strokes withcertainty.

The object of the invention is to provide a clock or time-measurergenerally with an arrangement or device for indicating the conclusion ofgiven intervals of time forthe benefit of nervous persons in a verygentle as distinguished from a distressing way and without the strokesof the clock sounding in an uncertain manner, as hitherto.

This invention consists in the combination of a clock or otherchronometer with a phonograph, graphophone, gramophone, or the like,which speaks out the words atthe conclusion of given time intervalsforinstance, on the hours and half hours.

The construction of the invention is shown in the accompanying drawingsin two forms.

Figures 1 and 2 are respectively an elevation thereof and a diagram ofthe conductors for electric working; and Figs. 3 and 4, re spectively,an elevation and a plan of the device for purely mechanical working.Fig. 5 is a detail of the roller and notched wheel.

In Figs. 1 and 2 are Very light spring-contacts a, arranged around theclock-face near the figures, and b is the small hand of the clock,provided with a fine yielding springj, by which it comes into electriccommunication with the spring-contacts a. The hand I) is connectedthrough a wire c, communicating with a source of electricity (1, with amagnet-bobbin e, and likewise the springcoutacts a are connected throughwires fand a main wireg with a magnet bobbin h, which is connected withthe other bobbin by a 0011- ductor t. The magnet-armature carries by arod Z a pawl m, which by the action of a counterweight n is adapted tolook a wheel 0 of a phonograph-roller 19, having on its peripherysuccessive impressions or indenta tions corresponding to the twelvefigures of the clock. The phonograph style can touch into theimpressions. The wheel 0 is provided with notches q, Fig. 5,corresponding in number to the time intervals to be called out, intowhich the pawl m can fall. At the end of an hour, when the hand 5 comesinto electrical communication with one of the spring-contacts a, Fig. 1,the pawl m is thereby relcased by reason of the bobbins e h attractingthe armature 7c, the clockwork as of the phonograph sets the roller 10of the same in rotation, the phonograph speaks out the correspondingnumber, and this being done the pawl m engages in the next notch of thewheel 0 and holds it and the phonographroller fixed until the nextcontact takes place, and so on.

In Figsn3 and 4 the arrangement of the phonograph-roller p and thenotched wheel 0 is as in the preceding example; but in this case thecounterweight n is actuated from a wheel 9 of the clock, said wheelbeing for this purpose furnished with triangular projections s, whichwhen the wheel turns engage the bent end 25 of the pawl m and press itdownward to release the pawl from the wheel 0 at the given timeintervals, thus permitting the movement of the phonographroller. When inthis way the number of the hour has been spoken out, the pawl 'm in thiscase also falls into the next notch and locks the wheel 0 with thephonograph-roller and its driving mechanism until the lapse of anotherhour. The counterweight n is sufficiently heavy to cause the end of thepawl to drop into the next succeeding notch q in the succeeding notchwithout fail.

"While in the example of Figs. 8 and at the calling of the hour isaccomplished directly at the clock, in that of the electric working thephonograph for calling out the hours can be located where desired, orseveral phonographs may be located each in a different place to call outthe time from one clock with which they are connected.

In both examples the phonograph roller may be provided withsounding-lines, for example, for giving off one or more call or alarmsounds preliminary to the call of the hour.

As in the example of Figs. 1 and 2, the contacts may be removed todifferent parts of the clock; so, also, in that of Figs. 3 and 4 may thephonograph-roller be locked from any other suit-able part of the clockand also by other means than projections, such ass, without affectingthe invention.

Having thus fully described my invention, I claim and desire to secureby Letters Patent- In a phonograph-clock, the magnets, the armature, thevertical rod secured to and moving with the armature, the counterweightconnected at its inner end to the vertically moving rod, and the pivotedlever also having its inner end connected to the rod, combined with aphonographic cylinder provided with a toothed wheel upon one end, withwhich the said pivoted lever engages; the clock, one of the hands ofwhich is provided with a suitably-shaped end for passingover thecontact-points arranged around-the dial, and the contact-points,suitable wires extendingthcrefrom connecting with the battery, and themagnets, substantially as shown.

In testimony whereof -I affix my signature in presence of two witnesses.

ERWIN TREITSCHKE.
